Magpul B.A.D. Lever

I have heard some differing opinions on the battery assist devices in the past. One side runs the heck out of them. The other side argues that the bolt catch on the AR isn't capable of holding the extra torque and breaking the bolt catch. The device itself looks like a good design and seems like it would help with one handed loading, holding bolt to rear, and malfunction clearing. But I also don't want to add something to my duty rifle that would negatively effect the reliability. Thoughts?
In my opinion anything that dangles into my trigger guard is an absolute no go. The risk of getting caught up on the lever, or slipping off on to the trigger is to high compaired to whatever percieved advantage the b.a.d. lever might have. I have heard of both these things happening to people I personally know as well as stories I have read on the internet. Think how much you are really going to use this device in any practical manner and compare that to the possable negative outcomes installing it may have. To me the b.a.d. lever adds "convenience" but at what cost? As far as reliability goes I haven't seen them effect the guns in that way myself.
I would also add that the ar 15 is an amazingly refined system and equally refined manual of arms. Adding things for the sake of convenience is often a step In The wrong direction. But this is only my opinion and I'm just one dude.
I used to run one on my personal rifle, but I wouldn't run one on my duty rifle because I read comments similar to those above. I realized that it was pointless to keep it on and potentially create a training scar. The only thing I really miss about it is the ease of locking the bolt to the rear and on the flip side of that, it's probably when I put the most stress on it causing the breakages we read about. I could see it being useful on a DMR type rifle to drop the bolt in the prone, but that's just a thought.

Aside from the potential issues with it being located inside the trigger guard and the aforementioned malfunctions, with the proper technique it's a rather unnecessary item to have on a rifle.
I ran one on a DD lower with a BCM upper for 40ish thousand rounds and had no issues. I got mine for the specific role of bolt catch/release duties in conjunction with a redi mod.

My take, if you're not running a redi mod there isn't a justifiable reason for it. I still think the redi mod is an excellent piece of gear.

I’m running a BAD lever on two of my rifles. I have not experienced any failures of the bolt locking back in about 3500ish rounds between the two, including a carbine class and two shoot house classes.
That said, it is only used for locking the bolt open or clearing double feeds. I do not use it to drop the bolt. The bad lever does give you a bigger target to hit when dropping the bolt with the left thumb.
YMMV but I like it so far.

I have used BADs on my duty rifles, Colt 6920 BCM , and my current set up for several years. It's been used in multiple classes, lots of rounds and a lot of manipulations. I have never had a malfunction caused by the BAD nor have I had one break. Bolt locks back proper on empty magazines and not prematurely. When I used a Redi-Mag it was essential. I have no problem doing demo's on our patrol rifles without them as far as that goes.

I've run them for many years professionally with no issues on duty guns and personal guns. Multiple Colt M4A1's, 6920's, BCM's, LMT, and a few franken guns. I initially had some work loose. The only mod I do is I insert a piece of bicycle inner tube rubber between the clamp and the bolt catch and ad blue loctite to the screw. They don't work loose after that. They've been on several guns I've shot multiple barrels out of. Lots of rounds and reps. You can live without it, we all did for years. It does make things easier though.
